Sandra,
I experience organ pain since developing RSD. I had the misfortune of passing kidney stones on about three occasions between 1988-1995, (2 from rt. kidney, 1 from left). (It was terribly traumatic pain!)
Occasionally, I get the same pain in my kidney and down into the urinary tract. IVPs show no new stones but I hurt just like the kidney stone event(s) are happening again...not to mention the groin/pelvic region pain! The first episode was enough to bring a grown man to lay curled up on the floor in pain. (From the day that first stone passed, I've had the utmost respect for women going through natural childbirth. Not that I didn't before, but the stone gave me perspective that I never would have known otherwise.

)
My Neuro told me that RSD can and does sometimes affect internal organs...I'm a witness to that.
